INSTALLATION
Remove all system power before
installation, first battery and then AC.
(To power up, connect the AC first,
then the battery.)
Unpack the MOM-4 and its attached back-
plate. Inspect it, looking for such things as
connectors not properly installed, dirt, and
packing material on the board.

MOM-4 Card Cage
OPERATION
The Model MOM-4 Card Cage board (See
Figure 1) provides the MXL/MXLV/MXL-IQ with
four card slots for optional modules. Each MOM-
4 has space for two full-width optional modules
or four half-width modules, or a combination of
one full and two half-width optional modules. The
MOM-4 comes with four card guides for mount-
ing two full-width modules. The half-width mod-
ules come with the necessary extra card guides
for mounting them.
NOTE: The MME-3 enclosure has up to three
locations for the MOM-4 (or for
OMM-1s, OMM-2s, or MOM-2s).
However, when a TSP-40 printer is
installed in an enclosure, it de-
creases the number of MOM-4s to a
maximum of two modules in that
enclosure.
The MSE-3L has one location for the
MOM-4.
The MOM-4 provides two power connector recep-
tacles, two power connection terminal blocks, and
two data connector receptacles. A 24 VDC cable
that provides the main power used by the optional
modules and an 8-wire ribbon cable for connection
of 5 VDC and data lines are provided with the
MOM-4 installation kit.
NOTE: TB5 is 24 VDC output only, with a
maximum of 2A.

1. Place the module vertically on the mounting
studs near the top left of the enclosure as
shown in Figure 3.
2. Fasten the MOM-4 in position with the
hardware provided.

Mounting Plate
The installation kit for the MOM-4 includes the
following items:
Four #10 nuts
Four #10 flat washers
Four #10 lockwashers
Four card guides
One 2-wire cable (P/N 555-190969)
Two 8-conductor ribbon cables (P/N
555-190967 and P/N 555-193344)
Mounting
(Refer to Figure 2)
To mount the MOM-4 card cage in an
MME-3 enclosure:
The MOM-4 mounts vertically on the lower
portion of the MBR-MP mounting plate under
the MMB or the PSR on the four studs provided
as shown in Figure 2.
1. Place the module on the mounting studs in
the left-hand position of the mounting plate.
2. Fasten the MOM-4 in position with the
hardware provided, as shown in Figure 2.
3. To mount any other MOM-4 modules used in
the system, repeat the above steps. Use the
center or right-hand position for the
additional modules as needed.
4. Once the MOM-4 is secured, install the four
card guides included in the package. Figure 3

Installing the Card Guides in the MOM-4
To install the card guides (See Figure 4):
Once the MOM-4 is secured, install the four
card guides included in the package. Mount the
four card guides to the positions shown in
Figure 4. The MOM-4 is shipped with mounting
screws for the card guides already installed.
1. Slip the slot in the base of the card guide
under one of the mounting screws.
2. Make sure that the locating pin on the guide
is seated in the hole on the MOM-4.
3. Tighten the screw.
Repeat this process for the remaining card
guides. The MOM-4 is now ready to accept the
optional modules.
Electrical Installation
There are two inputs that connect the MOM-4
with the MMB or SMB. These inputs provide all
the necessary power and data lines to support
the optional modules.
The first input is an 8-conductor ribbon cable.
Attach the cable to P6 on the MMB or SMB,
making sure that the locking rib on the cable
connector engages the locking tab on P6.
Attach the other end of the cable to P10 on the
MOM-4, again making sure that the locking rib of
the cable engages the locking tab on P10. This
cable supplies 5 VDC and communication be-
tween the MMB or SMB and the MOM-4.
The second input feeds 24 VDC full wave unfil-
tered DC to the MOM-4. This input connects to
either P8 (MMB-1 or SMB-1 only) or TB6. A 2-wire
cable is provided for backward compatability with
the MMB-1 or SMB-1. Connect one end of the cable
to P3 on the MMB-1 or SMB-1, making sure the
cable rib and board tab lock. Attach the other end
of the cable to P8 on the MOM-4 in the same way.
When the 24 VDC is provided by either the
MMB-2 or SMB-2 or the PSR-1, use TB6 on the
MOM-4 to connect the power. The wire for this
connection is not supplied (See MMB-2 Installa-
tion Instructions, P/N 315-095097, or PSR-1
Installation Instructions, P/N 315-090911, for
terminal connections.)
The power source on the MOM-4 is limited to 2A
max by the MMB-1 or SMB-1. Under maximum
load conditions, the optional modules must never
draw more than 2A from this connection.
firealarmresources.com
When the 24 VDC is provided by either the
MMB-2/-3 or SMB-2, use TB6 on the MOM-4 to
connect the power. The wire for this connection is
not supplied (See the MMB-2 Installation Instruc-
tions, P/N 315-095097, the MMB-3 Installation
Instructions, P/N 315-048860 or the SMB-2
Installation Instructions, P/N 315-095931).
When the system includes an MMB-2/-3 or
SMB-2, the maximum load current for the MOM-4
is 6A when using an MPS-6 and 12 amps when
using an MPS-12. However, the 6A must be
reduced by the amount of current being used by
the CZM-1, PS-5A/-5N7, and NAC outputs. Thus,
if the full 1A available to the CZM-1 and
PS-5A/-5N7, and the 3A available to the NAC
outputs are used, derate the MOM-4 current to 2
amps (or, if an MPS-12 is used, derate the MOM-4
current to 8A).
When the 24 VDC is provided by PSR-1, use
TB6 on the MOM-4 to connect the power. The
wire for this connection is not supplied (See the
PSR-1 Installation Instructions, P/N 315-090911,
for terminal connections).
When the system includes a PSR-1, the maximum
load current for the MOM-4 is 6A when using an
MPS-6 and 12 amps when using an MPS-12.
However, the 6A must be reduced by the amount of
current being used by the CZM-1 and PS-5A/-5N7
output. Thus, if the full 2A available to the CZM-1
and PS-5A/-5N7 are used, derate the MOM-4
current to 4A (or, if an MPS-12 is used, derate the
MOM-4 current to 10A).
Depending on the optional modules installed,
additional power may be available at TB5 and for
notification appliances. See Table 1 for the
maximum current required by each module under
full load conditions.
Determine which optional plug-in modules are used
in your CSG-M configuration. Depending on the
optional modules used, determine the outstanding
power by using Table 1 (See the EXAMPLE). This
power can be used for notification appliances or
for the optional power connector on TB5.

NOTE: When a CSM-4 is used, you may add
notification appliances to it if the maxi-
mum load current to the MOM-4 does
not exceed 2 amps (MMB-1 or SMB-1)
or with an MMB-2/-3, SMB-2, or PSR-1, 6
amps (MPS-6) or 12 amps (MPS-12).
Include the total alarm current on each
CSM-4 notification appliance circuit when
performing the calculations.
EXAMPLE:
With: one CRM-4 and one CSM-4
Total load current = 0.075 + 0.034 = 0.109A
With MPS-6:
Remaining Available Current =
2.0 - 0.109 = 1.891A (MMB-1 or SMB-1)
6.0 - 0.109 = 5.891A (PSR-1 / MMB-2/-3 / SMB-2)
with no CZM-1, PS-5A/-5N7, or NAC load
With MPS-12:
Remaining Available Current =
2.0 - 0.109 = 1.891 (MMB-1 or SMB-1)
12.0 - 0.109 =11.891 (PSR-1 / MMB-2/-3 / SMB-2)
with no CZM-1, PS-5A/-5N7, or NAC load
The remaining current may be used for alarm notifica-
tion appliances.
